Look at this picture.
Clearly, a probe or SCV can fit through and pass the zealot, right? It would take two zealots to block off the ramp completely or you would have to pull a probe (which is valuable mining time, especially at that time of game). Though, if you bought another zealot to block the ramp, that would cause a huge disturbance to your build order.
Now, look at THIS picture.
...One zealot blocks the ramp . Compared to the previous ramp, where TWO zealots have to block the ramp, or one zealot and a probe.
Now, I know this may not seem like a "big deal", but it is, this is experience talking. I was going for a standard DT rush build order against a protoss, but I wanted to do a ZCore build order, I did NOT want to pull a probe off, since its that early, thats valuable mining time, especially since I went 11 - Gas.
He squeezed by my zealot and scouted that I went DTs.
Again, its a bigger deal than it seems. It's NOT just a thing that happens every 100 games, this happens sooo much, I would say once in every 3 games. Scouting is a huge deal in StarCraft (obviously) and that one ramp completely makes scouting "imbalanced" (Lol, that sounds funny).
Now you might say "But... You can just move the zealot down a little bit and it will block it off 100%!".
That doesnt always work. I try to do that.
But heres a problem, if you move the zealot down, its on low ground and the scouting scv/probe will see that you blocked the ramp with your zealot, since its on low ground vision. So, the probe can just glitch by the zealot (which has happened to me dozens of times) and get in my main and scout.
Again, you may say "Ciara, one probe at that time does not matter".
That's what a lot of D+ players say. It is incorrect, period.
Anyways, now that I am done ranting, its time to do something about this "ramp" nonsense. Whenever we make maps, we need a ramp that can only be blocked by a single zealot. Everyone should start using these ramps if we find them. So what I REALLY am requesting, is a ramp that can be blocked by a single zealot.
None.
